Liverpool booked a Champions League semi-final showdown against Villarreal as the quadruple chasers survived a late collapse in Wednesday's 3-3 draw against Benfica. Jurgen Klopp's side already had one foot in the last four after winning 3-1 in the quarter-final first leg in Lisbon. They were on cruise control for long spells in the second leg at Anfield, but had to hold their nerve before advancing 6-4 on aggregate after an uncharacteristic meltdown in the closing stages. Ibrahima Konate put Liverpool ahead before Goncalo Ramos equalised late in the first half.
